Vital Viking Mechanics
Comfort & The Rested Bonus Guide
The Rested buff is the single most powerful status effect in Valheim. It doubles stamina and magic regeneration, boosts health recovery, accelerates all skill leveling by 50%, and counters harsh environmental penalties.
+100%
Doubles your stamina recharge speed (2.0x). Essential for continuous sprinting, dodging, parrying, mining, and weapon combos.
+50%
Accelerates passive tick healing by 1.5x. Synergizes with high-health foods and healing meads to survive heavy boss hits.
+100%
Doubles magic energy recovery (2.0x). Crucial for Mistlands and Ashlands mages maintaining Blood shields and staff barrages.
+50%
Grants 1.5x XP across every skill in the game (Swords, Bows, Running, Jumping, Blocking, Magic), cutting skill grind by a third.
The Comfort Duration Formula
Every longhouse begins at Comfort 1 (8 minutes). Each additional comfort level adds +1 minute of buff duration.
Warmth & Shelter
Rest near any fire source within 10 meters with roof overhead (minimum 80% enclosed). You must not be Wet, Cold, or near alerted enemies.
Quiet Meditation
Remaining in the Resting state for 20 continuous seconds awards the Rested status effect, granting full bonuses for your hall's comfort duration.
The Pocket Campfire Trick
Carry 2 wood and 5 stone in the wild. Drop a campfire and press X to sit next to it. You will gain 8 minutes of Rested on the go without any walls!

Select the comfort pieces present within 10m of your resting spot. Group items do not stack; unique animal rugs stack together!
Viking Mastery & Action Progression
Complete Skills System & Level 0–100 Scaling Guide
Every action in Valheim strengthens your Viking. Leveling skills expands your damage window from 25%–55% up to 85%–100% (more than doubling real DPS), slashes stamina and Eitr consumption by up to 50%, and accelerates draw, reload, and harvesting speeds.
+131%
At Level 0, weapons deal 25%–55% base damage (avg 40%). At Level 100, weapons deal 85%–100% base damage (avg 92.5%), more than doubling effective damage.
-33% to -50%
Physical attacks, tool swings, running, jumping, and spellcasting costs decrease linearly with skill level, enabling prolonged combat chains.
-5%
Dying reduces all skill levels by 5%. However, you receive a 10-minute 'No Skill Drain' buff protecting against consecutive death penalties.
+50% XP
The Rested buff grants a flat +50% experience boost to every skill action in the game. Always ensure your Viking is Rested before leveling skills.

Where do I find my Dedicated Server's Seed? (Valheim 1.0+, Linux, AMP, & Windows) ▼
Valheim 1.0 Save Format Change: In Valheim 1.0+, worlds are stored
as a folder named after your world (e.g.
worlds_local/Montanaheim/). Inside this folder, the legacy
.fwl file is replaced by _main.<N>.fwl2 (where
<N> is your latest save counter). Neither console logs nor
in-game pos commands display the seed.
- Linux Dedicated Server (AMP / LinuxGSM / Pterodactyl / Docker):
Check your server startup parameters for
-savedir(e.g.-savedir Saves). In your panel's File Manager or via SFTP, open<ServerRoot>/<savedir>/worlds_local/<WorldName>/(e.g.Saves/worlds_local/Montanaheim/). Open the most recent_main.<N>.fwl2file!
Via Terminal / SSH: Runstrings Saves/worlds_local/<WorldName>/*.fwl2 | head -n 4(Line 1 is world name, Line 2 is seed!). - Standard Linux (Default Path without -savedir): Located at
~/.config/unity3d/IronGate/Valheim/worlds_local/<WorldName>/_main.<N>.fwl2. - Windows Dedicated / Local Saves: Located at
%USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local\<WorldName>\_main.<N>.fwl2. - Instant Seed Extraction: You can open your
_main.<N>.fwl2file in Notepad/Notepad++ to see the seed near the top, or click "Load .fwl / .fwl2" above (or drag and drop the file onto this card) to extract the seed directly!
